Patented Sept. 24, 1929 earner orrlca FRANK CANNON, OF RHINECLIFF, NEWYORK DIRECTION-INDICATING SIGNAL Application filed September 20, 1927.

Thepresent invention relates to a direction indicating signalparticularly adapted for automobiles and has for its prime object toprovide a structure which may be mounted on an automobile or the like tobe seen from the front and rear and which embodies a pair of rotatingdisks operable by a pinion and rack structure through the medium of aplunger.

A still further important object of the invention resides in theprovision of a signal of this nature which is simple in itsconstruction, inexpensive to manufacture, strong and durable, thoroughlyefficient and reliable in use and operation, and otherwise well adaptedto the purpose for which it is designed.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Figure 1 is an end elevation of the signal embodying thefeatures of my invention,

Figure 2 is a vertical section therethrough taken substantially on theline 2-2 of Figure 1 Figure 3 is a top plan view of the signal showing aportion broken away in this sec- 30 tion,

Figure 4 is a vertical section taken substantially on the line l4@ ofFigure 2,

Figure 5 is an enlarged detail sectlon taken substantially on the line55 of Figure 4,

35 and,

Figure 6 is a detail section taken substantially on the line 6-6 ofFigure 2.

Referring to the drawing in detail it will be seen that the numeral 5denotes a cylindrical casing having end Walls 6 closing the same. Apartition 7 extends across the casing as a chord to form a segmentcompartment 8 the end wall 6 opposite this segment compartment 8 beingformed with openings having lenses 9 therein with protecting shades 1Othereabout and extending outwardly therefrom. A shaft 11 is journaled inthe end wall 6 coaxially with the cylindrical casing 5 and has fixed tothe end portions there- 50 of adjacent the end wall 6 disks 12 each of'16 is located in the compartment 8 so that Serial No. 220,812.

the lenses 9 by the rotation of the shaft 11 r as will be clearlyunderstood. The indicia on the transparent panels 15 will correspond sothat the same signal will be given to the rear and to the front of thesignal. A bulb the indicia opposite the lenses 9 may be easily read fromthe front and rear of the automobile on which the signal is mounted.This signal may be mounted on the windshield or any other part of theautomobile 5 by a clamp bracket 17 or in any other suitable manner. Inthe bottom of the cylindrical casing there is provided a cylinder 18with a plunger or piston 19 movable therein and a combined piston rodand rack bar 20 extending upwardly therefrom through an opening in thehead of the cylinder and meshing with a pinion 21 on the center of theshaft 11. A pipe 22 leads through the bottom of the casing 5 to theinterior of the cylinder 7 8 so that compressed air, exhaust gas, or thelike may be conducted into the bottom of the cylinder to raise theplunger or piston 19 and actuate the rack bar 20 and rotate the pinion21 for rotating the shaft 11 and the discs 12 to place the desired panel15 opposite the lenses 9 to give the desired signal.

A suitable circuit breaker 25 is disposed inside of the bottom of thecylinder 8 so that the plunger 19 will engage the same when in ,85

the bottom of the cylinder to break a circuit which will-include theelectric bulb 16 so that this electric bulb will be put out when thesignal is inactive, that is, when the plunger 19 is in the bottom of thecylinder.

It is thought that the construction, operation, advantages, and utilityof the invention will now be quite apparent to those skilled in this artwithout a more detailed description thereof. The present embodiment ofthe invention has been disclosed in detail merely by way of examplesince in actual practice it attains the features of advantage enumeratedas desirable in the statement of the invention and the abovedescription. It will be appar- 1 ent that changes in the details ofconstruction, and in the combination and arrangement of parts may beresorted to Without departing from the spirit or scope of the inventionas hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, What I claim as new is A signal ofthe class described comprising a cylindrical casing having vertical endwalls, a shaft journaled in the end walls co-axially through the casing,a pinion on the shaft within the casing, a closed vertical cylinderrising from the bottom of the casing, aplunger slidable in the cylinder,acombined plunger rod and rack bar engaged with the plunger and slidablymounted in the top of the cylinder and meshing with the pinion, a tubeleading to the interior of the bottom portion of the cylinder so thatfluid may be used for raising the plunger to rotate the shaft, the endwalls of the casing being provided with openings, and a disc on the endsof the shaft havin indicia which may be brought into registration withthe openings.

In testimony whereof I affix my signature.

FRANK CANNON.
